The Grizzlies signed guard Xavier Rathan-Mayes to a 10-day contract, the team announced Monday as it prepared to face the San Antonio Spurs at 7:30 p.m. in AT&T Center.

Rathan-Mayes, 23, recently played for the NBA G-League’s Westchester Knicks. He appeared in 39 games (37 starts) for Westchester and averaged 16.6 points, 6.4 rebounds, 7.1 assists, and two steals. Rathan-Mayes amassed 14 double-doubles and three triple-doubles.

The 6-foot-4, Canadian-born combo guard played college basketball at Florida State. He was not drafted in 2017.

The Grizzlies need immediate help in the backcourt because of injuries to Tyreke Evans (ribs), Andrew Harrison (wrist), Mario Chalmers (hamstring) and Mike Conley (heel surgery). Rookie Kobi Simmons was recently called up from the Memphis Hustle to add depth. He would be the only point guard available Monday when the Grizzlies face the San Antonio Spurs if not for Rathan-Mayes’ arrival.
